Soldier ant

“ The commonest of all the Indian ants, or at any rate the most conspicuous, are the black ones, to be found marauding on every sideboard, and whose normal state seems to be one of criminal trespass. These from their size are perhaps also the most interesting, as it requires little exertion to distinguish between the classes of individuals that in the aggregate make up a nest of ants. There is the blustering soldier, or policeman ant, who goes about wagging his great head and snapping his jaws at nothing ”

“ Sometimes somebody does come in the shape of another ant—the real ant this time, not the defenseless Neuropteron, but some valiant and belted knight from the warlike Formicidæ. Singly or in troops, this rapacious little insect, fearless in its chitinous coat-of-mail, charges down the tree-trunk, its antennæ waving defiance to the enemy and its cruel mandibles thirsting for termite blood. The worker white ant is a poor defenseless creature, and, blind and unarmed, would fall an immediate prey to these well-drilled banditti, who forage about in every tropical forest in unnumbered legion. ”

“ Mollie asked. "Can't they swim?"
"Ours couldn't; lots of them fell in the water and were drowned."
"Ants are usually quite helpless in the water," Miss Ruth said, "though a French writer who has made the little folks a study, tells a story of six soldier ants who rescued their companions from drowning. ”

“ A species of silvery-gray ant which was abundant in the glade was an object of special enmity, and even after one of these was killed and being carried along, passing army ants would rush up and give it a vicious, unnecessary nip. One such ant made its escape from the hold of a small worker; but before it had taken ten steps it was actually buried under a rolling mass of army ants. The flying leap with which these athletes make their tackle would delight the heart of any football coach, although their succeeding activities belong rather to savage warfare. ”

“ One could study for hours the interactions among the army ants themselves. More than once I saw a good-sized ant transporting one of its fellows, exactly as it would carry a bit of booty. I tried to examine this ant, and to my surprise, both attacked me ferociously. The one which was carried was neither dead, ill, nor disabled, but very much alive. I cannot even suggest an explanation of this phenomenon, as it did not seem an attempt to aid a comrade in distress. ”

“ They are content to live in the obscurity of their retreat under the green blades if unmolested. Should a blundering human being be tempted to take a seat upon the grass, they declare war and proceed to invest his person. Their feet cling, their tails sting; they tickle, and bite, and scratch until their unfortunate victim rushes headlong to the bathroom to dislodge and slay his enemies. Ants in England are not to be lightly trifled with, but they are mild compared with the Indian ant. ”

“ Its head, flat and square, is armed with two moveable crooked horns, whose singular structure shews how admirable Nature is, even in the least of her works.
This insect is the most subtle and dangerous enemy the ant has; the plans which he forms to ensnare his prey, are very ingenious. He mines a portion of land in the form of a funnel, at the bottom of which he waits to seize the ants, which coming by chance to the edge of the precipice, are thence hurried down to their merciless foe. ”

“ Their instincts deceived them, for that night it froze; rain, snow, and fog succeeded each other in turn, and when next he visited the ant-heap he found them lying in masses, stiff and dead, before the entrance to their dwelling.
Between the red and black ants there is great enmity, and terrible combats take place. When they fight they grasp each other like men wrestling, and each tries to throw the other down, and break his back. The conquered remain on the battlefield, nearly broken in two, and feebly waving their paws, till they slowly expire in agonies. ”

“ The creature lives in the tree-tops and is diurnal in habits. It moves along the branches with great rapidity, either in an upright position or inverted like a sloth, the prehensile tail being used constantly. Ants form the food, and as these ascend even the highest trees, the little ant-eater has a never-failing and abundant supply; they are gathered up hurriedly as the little creature moves quickly along.
One day an army of carnivorous ants invaded our quarters while we were busily occupied preparing the specimens collected during the morning. ”

“ Of all the enemies of the ant, those most dreaded are the ants themselves; the smallest not the least, since [459] several fasten at once upon the feet of the largest, drag them to the ground, embarrass their movements, and thus prevent their escape. One would be astonished at the fury of these insects in their combats; it would be more easy to tear away their limbs and cut them to pieces, than compel them to quit their hold. It is nothing uncommon to see the head of an ant suspended to the legs or antennæ of some worker, who bears about, in every place, this pledge of his victory. ”

“ I have no doubt that the primary object of these honey-glands was to attract the ants, and keep them about the most tender and vulnerable parts of the plant, to prevent them being injured; and I further believe that one of the principal enemies that they serve to guard against in tropical America is the leaf-cutting ant, as I have noticed that the latter are very much afraid of the small black ants. ”

“ It might easily have escaped from the ants by using its wings, but it would only have fallen into as great a danger, for the numerous birds that accompany the army ants are ever on the look out for any insect that may fly up, and the heavy flying locusts, grasshoppers, and cockroaches have no chance of escape. Several species of ant-thrushes always accompany the army ants in the forest. They do not, however, feed on the ants, but on the insects they disturb. ”

“ They accordingly pour a little treacle on the ground within a yard of the hole occupied by the white ants. The smell of the treacle shortly attracts some of the black species, who, on their arrival are not long in observing their old enemies passing in and out of the hole. Some of them leave the treacle; these are evidently messengers, as in the course of the day a whole army of black ants will be seen advancing, in a narrow line of many yards in length, to storm the stronghold of the white ants. They enter the hole, and they destroy every white ant in the building. ”

“ Experience has long ago taught him that to stray into the midst of a party of foraging ants is no slight matter. It would be like dancing an Irish jig over a nest of hornets. He is sure of being attacked, bitten, and stung by the venomous insects; and on hearing the call of the ant-thrush, he beats an instant retreat. The quadruped licking up his insect prey is a sight of less frequent occurrence. ”

“ The rufescent ant, in fact, is a purely military caste, which has devoted itself entirely to the pursuit of arms, leaving every other form of activity to its slaves and dependents. Officers of the old school will be glad to learn that this military insect is dressed, if not in scarlet, at any rate in very decent red, and that it refuses to be bothered in any way with questions of transport or commissariat. ”

“ Most of the newly developed males are ‘excess baggage.’ During the winged, or mating, stage they fly into the forest where the great majority of them are eaten by birds. When the surviving ants light on a tree, on the ground or on some other object, the wings drop off. Then they apparently wander about aimlessly until they come to an army ant trail which they recognize by the odor and follow it until they come to the colony which has made it. If this happens to be a colony of their own relatives, they probably are killed by the workers. ”

“ Each ant knows every other citizen of its own town, and an ant from any other town is immediately recognised as a foreigner. Ants have their overseers of industrial enterprises, and regular hours for work and sleep. The ant is the most pugnacious of all animals, and the most muscular compared with its size. It will boldly attack the biggest creature that walks if this creature invades its home. It will fasten its mandibles into an enemy, and allow itself to be torn to pieces without relaxing its hold. Among some savage tribes, certain species of ants are said to be used as surgeons. ”

“ Flocks of ant-birds usually follow in the wake of the army, feeding upon the ants and upon the insects that have been driven from their hiding-places. One of the questions that naturally arises in this connection is how the callow young of birds escape from the ants, as caged birds are not immune from their attacks, and dead or wounded birds placed near the army’s line of march are quickly discovered, torn to shreds, and carried away. ”

“ The ant-colony, powerful as we have seen it to be, and well protected as it undoubtedly is, is nevertheless subject to the attacks of enemies which wage a successful war against it. Certain species of ants appear to be more subject than others to the attack of such higher forms as the mammalian ant-eaters (Echidna and Myrmecophagidce) and armadillos, as well as to the onslaught of the insect ant-lion (Myrmeleo) . ”

“ I found out about some naughty, lazy ants, sir. Instead of taking care of their own homes and hunting up their own food, they go out to war against another kind of ant, which is living quietly and attending to its own business. All the grown-up ants these little fighters either kill or frighten so that they run away as fast and as far as their legs will carry them. Then these lazy ants steal the eggs and the babies. Some of them they eat on the way home, but most of them they carry to their underground galleries. There they take good care of them until they are grown up. ”

“ That she was challenged by a sentry ant—about as big to her as a bulldog to us—that the sentry gave the alarm, that the guard turned out from one of the ants' "cowsheds" over some of the green-fly, and that she went away in a hurry, with half-a-dozen furious ants on their hindlegs, trying to get hold of her retiring feet with their jaws, was a matter treated by her with insolent unconcern. ”

“ They were very chatty and agreeable, so we enjoyed ourselves very much.
"'Have you met the foraging ant?' asked one. 'They sally forth with officers to direct the movement. They are rather hot-tempered and cross, to be sure, attacking any one fiercely that may come in their path; yet they do a world of good. When it is known they are approaching, people open every closet, drawer, and box in their houses, that the ants may search and cleanse them. ”

“ They seem to attack persons out of sheer malice: if we stood for a few moments in the street, even at a distance from their nests, we were sure to be overrun and severely punished, for the moment an ant touched the flesh, he secured himself with his jaws, doubled in his tail, and stung with all his might. ”

“ They struck against each other when they met, and had always their mandibles separated in the attitude of defiance. As soon as the Herculean Ants approached their camp, the centinals in front assailed them with fury; they fought at first in single combat. The Sanguine Ant threw himself upon the Herculean Ant, fastened upon its head, turned its abdomen against the chest of its adversary or against the lower part of its mouth, and inundated it with venom. ”

“ Although an ant of ordinary size,—both in this and general appearance not differing greatly from the common red ant of England,—its bite and sting together are more dreaded than those of any other species. It crawls upon the limbs of the pedestrian who passes near its haunt, and, clutching his skin in its sharp pincer-like jaws, with a sudden twitch of the tail it inserts its venomous sting upon the instant, holding on after it has made the wound, and so tenaciously that it is often torn to pieces while being detached. It will even go out of its way to attack any one standing near. ”

“ Belt believes, after much careful observation, that these ants protect the plant they live on from leaf-eating insects, especially from the destructive Saüba ants,—that they are in fact a standing army kept for the protection of the plant! This view is supported by the fact that other plants—Passion-flowers, for example—have honey-secreting glands on the young leaves and on the sepals of the flower-buds which constantly attract a small black ant. ”

“ The earth would shake under their tread; forests would fall before the power of their jaws; the elephant himself would be unable to resist their onset. Even now all smaller animals fly in terror at the approach of an ant army, and if overtaken fall victims to their furious assaults. Such an army, were the individuals no larger than mice, would yet be irresistible. Among the many reasons man has for gratitude to Providence, not the least is that the ant was not endowed with bulk in addition to its other gifts. ”

“ When, however, the angry insect finds that menace is ineffectual, and that it cannot alarm the foe, it settles the matter by dropping to the ground. If an ant-infested tree be suddenly struck with a stick, the ants tumble down in all directions, falling quite unconcernedly from a height of fourteen or fifteen feet, and rattling like hail upon the dried leaves at the foot of' the tree. When they reach the ground, they lie motionless for a moment, and then pick themselves up and run away as if nothing were the matter. ”

“ When he has sucked all the juices from her body, he contrives to eject from his habitation the dry and hollow carcase, repairs any damage his trench may have sustained, and puts himself again in ambush. He does not always succeed in seizing his prey at the moment of its fall; it frequently escapes him, and endeavours to remount the funnel; but then the ant-lion works with his head, and causes a shower of sand to descend upon his captive, and precipitate it once more to the bottom. ”
